The MongoDB developers have announced the release of version 1.8 of their open source, scalable, document-oriented database. Arriving just over seven months after the release of the previous stable major version, 1.6, this new release is a drop-in replacement for 1.6 and includes many new features. Most notably a journalling storage engine has been added, as well as support for covered and sparse indexes, together with bug fixes and other improvements.
